The Goddess Path: Myths, Invocations, and Rituals by Patricia Monaghan
This book is very similar to Goddess Companion: Daily Meditations on the Goddess by the same author (review here) in that it draws from many different traditions to show different aspects of the goddess. What this one does, however, is instead of daily meditations, it's separated into 20 chapters. Each chapter focuses on a different goddess, providing snippets of poetry, myths, rituals, and explanations of the goddess and what she stands for. At the end of each chapter is a list of questions to ask yourself to better relate to the lesson each goddess has to teach. The goddesses included range from Isis to Oshun, from Kali to Brigid, from Artemis to Kuan-Yin to Gaia.
Chapters are generally organized as follows:
Bits of poetry/song
Myths and Meanings
Suggestions for Invoking
Questions and Activities
I really enjoy this book for learning more about the goddesses, as well as the ideas for rituals involving them.
